Rising Diabetes Prevalence among Urban-Dwelling Black South Africans

Diabetes has globally emerged as a major public health challenge of the 21stcentury. Sub-Saharan Africa (SSA), where diabetes was considered rare prior to the 1990s, has also witnessed a rise in the burden. Studies conducted 10–20 years ago found that diabetes prevalence varied across the region. There are, however, limited data as to the extent of the rise. In urban Tanzania rates increased from 0.3% in the 1980s to 4.6% in 1996 according to the 1998 WHO criteria, and in urban Cameroon from 1.5% in the 1990s to 6.6% in 2003.
